Our Gemini 2.5 tech report ✨ is finally out on arXiv -- grateful for the collaboration with brilliant colleagues! arxiv.org/pdf/2507.06261
Great overview on the parallelism techniques needed for LLM training/inference from the new CS336 class at Stanford (Tatsunori Hashimoto & Percy Liang): youtube.com/watch?v=l1RJcD…. Info-dense and doesn't shy away from the technical details!

More than 5x growth in paid trips from this time last year — each ride contributing to safer streets and more accessible mobility for all. Here’s to millions more!
We’re now providing more than 250,000 fully autonomous paid rides each and every week. The robotaxi future is here, and it’s powered by our generalizable Waymo Driver 🤖🚘
Thrilled to share that the amazing work of @stan188249301 (@maxjiang93's and I's intern at Waymo Research last summer) is accepted to CVPR 2025! SceneDiffuser++ fulfills a vision we've had in mind for several years, and we weren't sure if it was even possible. More details soon!
🥁Introducing Gemini 2.5, our most intelligent model with impressive capabilities in advanced reasoning and coding. Now integrating thinking capabilities, 2.5 Pro Experimental is our most performant Gemini model yet. It’s #1 on @lmarena_ai leaderboard. 🥇
Highly recommend this diffusion lecture by Sander Dieleman: youtube.com/watch?v=9BHQvQ…. Uncommon to hear these principles discussed with such clarity. CFG becomes obvious when we consider geometry (magnify direction in space to make samples look more like the conditioning info).

In May, we announced that we were offering 50k weekly trips. Today, we’re excited to share that we have doubled that number — all while ensuring a safe and delightful experience to our riders.
We’re building a safer future one ride at a time, and I’m thrilled to share that we've just surpassed 100k paid trips per week! Congratulations to the entire @Waymo team on this incredible milestone, and thank you to our riders who make this journey possible.
Thank you Alphabet, Waymonauts, and, thank you Waymo One riders! This is a testament to the milestones we’ve reached together and the many more to come as we improve road safety and advance the World’s Most Experienced Driver. Cheers!
Alphabet has committed up to $5B to @Waymo. We are grateful for their immense vote of confidence in our team and recognizing the amazing progress we’ve made with our technology, product, and commercialization efforts.
